I have to agree. I suspect something amiss with the pushbutton. One problem is this for me is a 20 year leap in technology. I've had little experience with FM. I am fine on rotary waveband circuits of the 50's era. If it becomes absolutely necessary I will remove the pcb and with great care. For now I seem to have the oscillator resistor identified. I will test the grid bias too. Cleaning helps to see the soldered points.
